Security researchers at ARMO have found a high-severity vulnerability in the Kyverno admission controller container image signature verification mechanism. The vulnerability enables an attacker who is either running a malicious container image registry or is able to act as a proxy between the registry and Kyverno, to inject unsigned images into the protected cluster, bypassing the image verification policy. The vulnerability was introduced in version 1.8.3 and was fixed in version 1.8.5.

A review of recent Kroll incident response cases consistently proves that the healthcare industry is one of the most frequently targeted sectors. This observation mirrors what is experienced by national cybersecurity agencies as multiple warnings have been launched during 2022, highlighting how ransomware gangs and nation state actors are now aggressively targeting healthcare institutions.

Controlling and filtering traffic when containerizing a workload within Kubernetes Pods is just as crucial as a firewall in a more traditional network setup. The difference is that, in this scenario, those capabilities are provided by the Kubernetes NetworkPolicy API. This article will explore Kubernetes NetworkPolicy by creating an example network policy and examining its core parameters. Then, we’ll look at some common NetworkPolicy use cases and learn how to monitor them using kubectl.

Personal data such as email addresses and passwords unlock our online identities and have become part and parcel of almost all accounts on the internet. Research indicates that there are over 5 billion daily web users worldwide and mobile phones account for about 60% of the world’s web traffic. Digital data examples include text messages, videos, satellite images and data from IoT, smart devices and social media.

In predicting what will transpire in cybersecurity in 2023, the best method is to look at past experience. As with any security and criminal activity, threat actors tend to build upon what they have done in the past, adding new twists to keep their tactics fresh and effective. So, taking this into consideration, it is no surprise that Trustwave's security experts see much of the same type of attacks that plagued 2022 continuing.

As demand for greater security visibility accelerates, SecurityScorecard Marketplace, the one-stop shop for trusted SecurityScorecard partner solutions, has gained significant momentum. In 2022, the Marketplace partner ecosystem expanded by 80% to now include more than 90 technology and integration partners, including OneTrust, Coupa, CSC, CrowdStrike, IBM, Splunk, and Snowflake.

Challenge Accepted is a podcast from Arctic Wolf that has informative and insightful discussions around the real-world challenges organizations face on their security journey. Hosted by Arctic Wolf’s VP of Strategy Ian McShane and Chief Information Security Officer (CISO) Adam Marrè, the duo draw upon their years of security operations experience to share their thoughts and opinions on issues facing today’s security leaders.

Each year, cyber attacks and data breaches are becoming more devastating for organizations. According to the 2022 Cost of a Data Breach Report by IBM, the global average cost of a data breach reached a record US$4.35 million in 2022. However, security teams are often not ready to detect all security gaps in their organizations. The scope of their monitoring is usually so broad that it’s challenging to anticipate where a potential threat might come from.

Firewalls are the first line of defense in any network. Firewalls can be software or appliances, and organizations can configure them up to allow or disallow some or all IP traffic, or to verify specific traffic types based on rules that use deep packet inspection. For maximum effectiveness, it’s critical to monitor the operation of your firewalls to spot threats and misconfiguration.

Hardening the various systems across your network helps you improve your cybersecurity posture level and block attacks. Hardening includes regular patching of known software vulnerabilities and turning off nonessential services on each system to reduce the number of processes that can be exploited. Hardening your database servers is a vital part of this information security strategy.
